I asked a friend to refer me. The recruiter called right after, which was very efficient.

However, to schedule the phone screen, it took two weeks. After another week, they scheduled the onsite, which had five rounds.

Almost every round followed the same pattern: coding + coding/design, so basically around 10 questions in total. Only one interviewer asked for background questions.

Overall, the interviewers were all very nice, except for one who spent most of his time on his phone and had some incorrect understanding of a basic data structure.

NDA. For coding/algorithm, just check out LeetCode.
